Australia's Cooper Energy Limited disclosed Monday that the Bunian-4 appraisal/development well in the Tangai-Sukananti KSO, South Sumatra, Indonesia has reached a total depth of 5,721 feet (1,744 meters). Wireline logging of the wellbore and installation of production casing is complete and preparations are being made to flow test the well.

Preliminary results indicate that Bunian-4 has intersected 17 feet (5.2 meters) of net sand in the TRM3 Sandstone section 56 feet (17 meters) high to prognosis. The top of the primary target TRM3 Sand was intersected 1,542 feet (470 meters) east-southeast and 20 feet (6 meters) below the producing TRM3 Sand at Bunian-3. In addition to the successful appraisal of the TRM3 Sand a new zone designated the GRM Sandstone is identified as potentially hydrocarbon bearing. The net sand thickness intersected at the GRM Sandstone is 11 feet (3.5 meters).

Potential in the secondary objective TRM1 and TRM2 Sands will be evaluated when the interpretation of wireline logs is complete.

Production casing has been run and a multi-zone production completion will be installed to allow each of the major hydrocarbon zones identified to be flow tested and produced independently shortly after the release of the drilling rig.

Cooper Energy Managing Director, David Maxwell said “the preliminary results from Bunian-4 are very encouraging, particularly the TRM3 Sand and the possibility of a new pool discovery in the GRM Sandstone”.

Further announcements will be made once flow test results are known and when the impact on reserves is established.
